High jeweler GRAFF unveiled The Hallucination "Phantom," a jewelry watch made with multicolored diamonds, at Baselworld 2014, the world's largest jewelry and watch fair.

This watch, featuring a kaleidoscope of more than 110 carats of colored diamonds, was conceived by Laurence Graff, founder and current chairman of Graff. It took thousands of hours of craftsmanship by the design team and other specialists. Graff is known as the ultimate jeweler, specializing in the finest and rarest diamonds from around the world and handcrafting their pieces. The Hallucination "Phantom" is priced at 5.5 billion yen, making it the most expensive watch Graff has ever produced.

Lawrence commented, "This watch is a work of art that celebrates the miracle of colored diamonds. For many years, I have wanted to create an extraordinary watch that would fully express our passion for diamonds, and The Hallucination is a dream watch that has fulfilled all of my passion for diamonds."
